E-Control Systems, Inc (ECS) introduces a new line of sensors to complement its wireless temperature monitoring system. The new sensors accurately monitor ultra-low temperature freezers and liquid nitrogen tanks, expanding the capacity to monitor temperatures between -80°C and -200°C. The addition of these sensors expands ECS’s existing wireless temperature monitoring system by providing a complete solution for the pharmacy. The new sensors work seamlessly on the existing ECS platform and alert the end user when equipment temperatures fluctuate from the acceptable range.
